To (LZZ whom t may concern: Y

Beit known that we, HENRY D. JEFFREY and JACOB LIVER, of Winona, in the county of Vinona and State of Minnesota, have invented a new and useful Improvement in Bob- Sleighs, of which the following isafull, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specitication, in which similar letters of reference indicate corresponding parts in all the gures.

Figure l is a plan view of the forward bob of a bob sleigh, the bolster being omitted, the king-bolt shown in section, and the tongue broken away.- Fig. 2 is a sectional side elevation of the same taken through the broken line xx, Fig. l. Fig. 3 is a rear elevation of a part of the same enlarged, the runner and rave beiugshown in section andl part of the cap-being broken away. Fig. 4 is a sectional plan view of the knee taken through the line y y, Fig. 3,r and showing a part of the runner. Fig. 5 is a bottom view of the cap, the arms ofthe clip-bows being shown in section.

The object of this invention is to provide bobsleighs constructed in such a manner that the knees will form double-acting connections between the runners and beams, and will thus allow the sleighs to work easily,while forming a rm, substantial, and durable support for the beams.

A further object of this invention is to keep the front beam always in an upright position, make the draft of the rear bob come directly upon the tongue, and allow the reach to be used with a loose coupling.

The invention consists in the construction and combination of various parts of a bobsleigh, as will be hereinafter fully described and then claimed.

A represents the runners, to the forward ends of which are pivoted the ends of the roller B of the tongue C.

To the runners A are attached plates D, upon which rest the lower ends of the kneestandards E, the bodies of which are made oval in form, and have grooves in their front and rear sides to receive the rave-pins F, that keep the said standards in place. The rave- (T'o model.)

pins F pass up through the runners A, and their heads are countersunk in the faces 0f the said runners, as indicated in dotted lines in Figs. 2 and 3, and are covered by the runner shoes G. rlhe upper ends of the rave-pins F pass through holes in the raves H, the middle parts of which rest in recesses I, formed4 to receive them in the upper ends ofthe standards E.v The end parts ofthe raves H are inclined downward, and their ends are secured to the runners A in front and rear of the knee-standards E by bolts J, clips, or other suitable means. The standards E are made hollow, as shown in Fig. 4, to allow them to have a suitable size and strength without being too heavy.

Upon the outer and inner sides of the upper ends of the standards E are formed arms K, the upper sides of which are rounded and slightly tapered from their inner ends toward their outer ends.

Upon the upper side of the arms K rest concave bearings, formed in the lower sides of the caps L, so that the said caps L can rock upon the said arms K, while the taper of the said arms allows the said caps to have a lateral play. The outer ends of the arms K are of less width than the ends of the bearings in the caps. the horizontal oscillation as well as the vertical rocking movement of the tapered arms in the said bearing, so that/a universal joint is obtained.

The standards E and caps L are connected with each other and with the beam M by clips, the bows N of which rest in grooves in the lower sides of the outer ends of the arms K, and in recesses in the lower edges of the lugs O, formed on the lower parts of the sides of the caps L. The arms of the bows N pass along grooves in the sides of the caps L, pass through holes in the beam M, and through holes in the yokes P, and havenuts Q screwed upon their upper ends.

Upon the lower sides of the middle parts of the caps L are formed projections R, the bottoms of which are rounded, and which t into the recesses I and rest upon the raves H, so as to take the strain from the arms K This construction allows of and give an easier lateral movement to the caps L. lith this construction the caps L can rock upon the arms K and raves H, so that the beam M can remain stationary, while the runners A incline upward or downward inpassing over uneven ground. NVith this construction also the caps L can have a lateral movement upon the arms K of the standards E, so that one of the runners A can move a little inadvanee of the other, which freedom of movement greatly facilitates the starting ofthe sleigh when heavily loaded. Another advantage of this construction is that when heavily-loaded sleighs have to be drawn out of orinto the road to pass other sleighs,or for other purposes, the runners can be turned at an angle of about twentyiive degrees (25) without wrenching or twisting the load, so that the loaded sleigh can be turned to one or the other side with ease.

To the rear end ot' the tongue C is secured, by a belt, S, or other suitable means, the iorward end of the chain T, the rear end of which is secured by a link or clevis, U, and the king-bolt V,or other suitable mcans,to the beam M. The king-bolt Vpivots the bolster to the beam M in the ordinary manner. which bolster is not shown in the drawings, as there is nothing new in ils construction or opera. tion. By this construction the draft ofthe rear bob will come directly upon the tongue and not upon the beam, front roller, runners. clips, and the joint-connection between the beam and runners, thus leaving the joint perfectly free from all strain, except the weight ofthe load upon it; andthe beam will be kept always in an upright position, and cannot tip backward, as is the case with ordinary oscillating bob-sleighs in which the draft comes upon the front roller, runners, oseillatingjoint. and beam, and tips the said beam to the rearward, and is liable to bend or break the said king-bolt or the reach. This construction also allows the reach to be attached to the front bob with a loose coupling, which cannot be done on an oscillating sleigh when the chain T is not used.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent-- l. The combination,with theknee E, having the transverse rounded arms K, having a 1ongitudinal recess, I, and tapering outward slightly from said recess, of cap L, having a projection, R, on its under side fitting within the recess I, and concavities on opposite sides of the said projection to receive the upper rounded and tapered surfaces of the arms K, the said concavities being of greater width than the tapering arms, whereby arocking and a lateral movement is afforded, substantially as and for the purpose set forth.

2. The combination, with the cap L, provided on its under side with the projection R, rounded recesses tapering` outward from opposite sides of said projection, and recessed depending lugs O on opposite sides of the ends of the said recessed parts of the knee 1C, having a longitudinal recess, I, on its top, rounded arms K, tapered outward from opposite sides of said recess and resting in the recesses of cap L, the recesses being otgreater width than the tapering arms, the clips N, fitting in the recesses ot' lugs O, and holding the cap and k nee together, substantially as set forth.

3. Thecombinatiou, with the knee E, having the longitudinal recess I and the rounded outward tapered arms K ou opposite sides of said recess, ol' the rave H, resting in the bottom ot' recess I and bent downward at opposite sides thereof', the cap L, provided with the projection Pt, fitting in recess I and resting on the rave H, the cap being recessed to receive the arms K and rock and oscillate laterally thereon, substantially as set forth.

4t. The combination, with the runners A and the cross-beam M, ot' the knees E, having lougitudinal recesses I, and rounded outward tapered arms K on opposite sides ofsaid recesses, the rave-bolts extending upward from the ruuners in front and rear ofthe knees E, the raves H resting between their ends on the bottoms of the recesses l, apertured to receive the upper ends ot' the rave-bolts, and bent therefrom downward and secured to the runners, the caps L, having central projections, It, resting on the raves within the recesses I, rounded recesses receiving the arms K, and grooved lugs O on opposite sides of the ends of said grooved portions, and the clips N, passed upward through the grooves in said lugs and secured to the beam M, substantially as set forth.
